The purpose of this study is to analyze the experience of the parents who examined the first infant oral examination and to understand how to improve the practical oral examination business. In-depth interviews were held with 10 parents who did the first infant oral examination, and their children's age was less than 18 to 29 months. The following conclusions were obtained by deriving the concepts and categories of the recorded contents. First, the main reason for the unsatisfactory examination of this study was that it was formal. Parents were disappointed in the fact that they did not look at the mouth of the child at the same time as it was fast and they said because it is carried out free of charge, it is more formal than the examination for general dental treatment. Second, most of the participants questioned whether they should resume infant oral examination. Third, it appears that the tooth number or dental terminology in the result notice is difficult to understand. Fourth, the opinion on the improvement of the infant oral examinations was should provided that the oral health management information after examination and the direct oral health management method education at the examination. In addition, we identified the need for parents' oral health care education for infants. Therefore, it has been confirmed that in order for the infant oral examination and young children to be practically carried out, the problems should be improved by collecting opinions of the parents. Also it is necessary to search for efficient business management method through repeated research related to infant oral examination.

Purpose: Excess sodium intake may contribute to the etiology of hypertension and cardiovascular disease risk. World Health Organization (WHO) recommends a daily sodium intake of less than 2 g. The aim of this study was to estimate the association of sodium intake with obesity in Korean adults. Methods: This study used Dietary intake and Health data on 22,321 subjects aged 30 years and over from the Korea National Health and Nutrition Examination Survey (KNHANES) 2010~2014. Information on dietary intake was obtained by the one day 24-hour recall method in KNHANES, and sodium intake was classified into five groups (< 2,000 mg, 2,000~4,000 mg, 4,000~6,000 mg, 6,000~8,000 mg, ${\geq}8,000mg$). Obesity was defined as having a body mass index (BMI) higher than $25kg/m^2$. Intake of sodium and obesity status were analyzed by logistic regression with SPSS Statistics 23. Results: Men tended to have a higher sodium intake than women (p < 0.001). After adjusting for age, sex, year, daily energy intake, education level, smoking status, drinking status, physical activity, and chronic diseases and comparing the highest sodium intake group (${\geq}8,000mg$) with the lowest intake group (< 2,000 mg), the OR of obesity was 1.351 (95% CI: 1.032~1.767) in men. The OR of obesity in the sodium intake group (4,000~6,000 mg) was 1.232 (95% CI: 1.063~1.427) in women. Conclusion: Our findings suggest an independent relationship between sodium intake and as increased risk of obesity in Korean adults, implying the necessity for future research on low-sodium diet intervention in relation to obesity.

The purpose of this study is to classify the underlying and parsimonious types of child maltreatment and examine whether the effects of risk factors on child maltreatment recurrence differ by type of maltreatment. We utilized the multiyear national administrative data from the National Child Maltreatment Information System collected by Child Protection Agency in Korea. Of 26,921 child maltreatment victims reported and substantiated on or after January 1, 2012, 1,447 children who had recurrence of child maltreatment until December 31, 2015 were selected as maltreatment recurrence group and 4,580 children who had not experienced maltreatment since first substantiation were assigned as maltreatment non-recurrence group. Latent class analysis(LCA) and latent transition analysis(LTA) were used to group children with similar maltreatment subtypes into discrete classes of child maltreatment recurrence. Logistic regression is employed to examine the association between the child maltreatment predominant types and risk factors for recurrence. Results of LCA and LTA showed four latent classes representing predominant type of child maltreatment: 'physical abuse predominant type', 'emotional abuse predominant type', 'sexual abuse predominant type', and 'neglect type'. Significant differences in the effect of risk factors among latent classes were found in child's age and gender, perpetrator's gender, family poverty, biological parent as the perpetrator, domestic violence toward partner, perpetrator's alcoholic problem, insufficient parenting skills, and out-of-home care service, Based on these findings, results suggested how the typology can be used to guide decision about who to target in prevention and intervention programs, and which features of risk factors to target. Practice and policy implications as well as further research tasks were discussed in the lights of searching for useful and important strategies to prevent recurrence of child maltreatment.

Objectives : Living donor liver transplantation (LDLT) is a life-saving therapy for patients with terminal liver disease. Many studies have focused on recipients rather than donors. The aim of this study was to assess the emotional status and personality characteristics of LDLT donors. Methods : We evaluated 218 subjects (126 male, 92 female) who visited Daegu Catholic University Medical Center from August 2012 to July 2018. A retrospective review of their preoperative psychological evaluation was done. We investigated epidemiological data and the Minnesota Multiphasic Personality Inventory-2 questionnaire. Subanalysis was done depending on whether subjects actually underwent surgery, relationship with the recipient, and their gender. Results : Mean age of subjects was $32.19{\pm}10.91years$. 187 subjects received LDLT surgery (actual donors) while 31 subjects didn't (potential donors). Donor-recipient relationship included husband-wife, parent-children, brother-sister etc. Subjects had statistical significance on validity scale L, F, K and all clinical scales compared to the control group. Potential donors had significant difference in F(b), F(p), K, S, Pa, AGGR, PSYC, DISC and NEGE scales compared to actual donors. F, D and NEGE scales were found to be predictive for actual donation. Subanalysis on donor-recipient relationship and gender also showed significant difference in certain scales. Conclusions : Under-reporting of psychological problems should be considered when evaluating living-liver donors. Information about the donor's overall psychosocial background, mental status and donation process should also be acquired.

This study examines the characteristics of 24 Korean hidden champions such as key success factors, core competences, strategic problems, and desirable future directions. The study categorized them into 8 types with Danny Miller's four trajectories and top manager's decision making style(rationality and passion). Danny Miller argued in his book, Icarus paradox, that outstanding firms will extend their orientations until they reach dangerous extremes and their momentum will result in common trajectories of decline. He suggested four very common success types: Craftsmen, Builders, Pioneers, Salesmen. He also suggested common trajectories of decline:Focusing(from Craftsmen to Tinkers), Venturing(from Builders to Imperialists), Inventing(from Pioneers to Escapists), Decoupling(from Salesmen to Drifts). In Korea, successful startups appear to possess three kinds of drive: Technology-drive, Vision-drive, Market-drive. Successful technology-driven firms tend to grow as craftsmen or pioneers. Successful vision-driven and market-driven ones tend to grow as builders and salesmen respectively. Korean top managers or founders seem to have two kinds of decision making style: Passion-based and Rationality-bases. Passion-based(passionate) entrepreneurs are biased towards action or proactiveness in competing and getting things done. Rationality- based ones tend to emphasis the effort devoted to scanning and analysing information to better understand a company's threats, opportunities and options. Consequently this study suggested 4*2 types of Korean hidden champions: (1) passionate craftsmen, (2) rational craftsmen, (3) passionate builders, (4) rational builders, (5) passionate pioneers, (6) rational pioneers, (7) passionate salesmen, (8) rational salesmen. These 8 type firms showed different success stories and appeared to possess different trajectories of decline. These hidden champions have acquired competitive advantage within domestic or globally niche markets in spite of the weak market power and lack of internal resources. They have maintained their sustainable competitiveness by utilizing three types of growth strategy; (1) penetrating into the global market, (2) exploring new service market, (3) occupying the domestic market. According to the types of growth strategy, these firms showed different financial outcomes and possessed different issues for maintaining their competitiveness. This study found that Korean hidden champions were facing serious challenges from the transforming economic structure these days and possessed the decline potential from their success momentum or self-complacence. It argues that they need to take a new growth engine not to decline in the turbulent environment. It also discusses how firms overcome the economic crisis and find a new business area in promising industries for the future. It summarized the recent policy of Korean government called as "Green Growth" and discussed how small firms utilize such benefits and supports from the government. Other implications for firm strategies and governmental policies were discussed.

The purpose of this study was to investigate the regional differences in anthropometric measurement, dietary behavior and nutrient intake among the nation-wide college students participating in a nutritional education program via internet. The subjects were 1614 college students (male: 752, female: 862) and divided into 4 regional groups. A cross-sectional survey was conducted using a self administered questionnaire, and the data were collected via internet or by mail. The nutrient intake data collected from food record were analyzed by the Computer Aided Nutritional Analysis Program. Data were analyzed by SPSS 10.0 program. Average age of male and female college students were 23.6 years and 21.0 years, respectively. Most of the male and female college students had poor eating habits, such as unbalanced meals and skipping meals. In particular, more than 60% of the male college students in Chungcheong and Gyeongsang areas had irregularity of meal time. Female students in Seoul and Incheon areas showed significantly higher consumption frequency of yellow and green leafy vegetables compared to Chungcheong and Gyeongsang areas. Female students in Seoul, Incheon and Chungcheong areas showed significantly higher consumption frequency of milk and milk products compared to Gyeongsang area. Calorie, vitamin A, calcium and iron intakes of the male students and calorie, vitamin A, vitamin $B_2$, niacin and calcium intakes of female students were lower than the Korean RDA. Female students in Incheon area showed significantly higher vitamin C and iron intakes compared to the other areas. These results provide a nation-wide information on dietary behavior and nutrient intake among Korean college students.

Serological evaluation for the poultry is important for various reasons, such as designing and assessing the vaccination program and diagnosing diseases and for this reason, serologic tests for the layer flocks have been conducted on a regular basis. Moreover, the nationwide serological survey and analysis are essential to understand the epidemiological status of national poultry industry. In this sense, the study was conducted to evaluate the immune status of the layer flocks with the sera submitted to Avian Disease Laboratory, Chungbuk National University in 2009, and several important viral diseases were selected for evaluation including low pathogenic avian influenza (LPAI), Newcastle disease (ND), infectious bronchitis (IB) and avian metapneumovirus (aMPV). For LPAI and ND, the age-related patterns of geometric mean titer (GMT) changes were similar but there were differences in the flock positive rate and the level of GMT due to the different vaccination policy. In the case of IB, the values of GMT showed that the field infection was more prevalent than expected. For aMPV, positive birds in a flock increased as the layers got older, which reflected the course of field infection because vaccination against aMPV was not allowed in 2009. From this study, the immune status for the main viral diseases in layers became more clarified but this information was limited because of only one year study. Therefore, serological survey needs to be conducted on a yearly basis and furthermore include broilers and breeders for a better understanding of the health status in the national poultry industry.

In order to get information for the improvement of feeding systems of egg-type layers, a dietary self-selection study was conducted. Corn diet, soybean meal diet, wheat bran diet, soybean meal+fish meal diet, and limestone diet were individually prepared for self-selection regime. Forty brown layers were offered either a control laying diet (C) or one of the 3 self-selection regime consisted of corn-soybean meal-limestone diet ($T_1$), corn-soybean meal-wheat bran-limestone diet ($T_2$) and corn-soybean meal+fish meal-wheat bran-limestone diet ($T_3$) for one wk each at 31 wk and 41 wk of age. In all dietary treatments, most of the eggs were laid from 0700 h 1300 h and hens consumed more feed, energy and protein on egg forming days than on non-forming days. On egg forming days, hens fed self-selection regime consumed less energy and protein than those fed control diet. On egg forming days, the consumption of feed, energy and protein increased continuously from 1000 h 2200 h in the control diet group but they decreased during the last 3 hours from 1900 h to 2200 h in self-selection regime groups. Up to 1600 h, calcium intake of the self-selection regime groups were much less than that of the control group but after that time, they increased markedly and were much more than that of the control group. The results of the study suggest that the practical self-selection regime for layers should be developed to meet the daily cyclic requirement for nutrients without consuming an excess energy and protein at certain times of the day.

Purpose: The aim of this study was to evaluate the clinical usefulness of ultrasound examination of children performed by a pediatrician. Methods: One thousand children who presented with symptoms of a gastrointestinal disorder and underwent abdominal ultrasound evaluation in the Department of Pediatrics, between January 2003 and June 2006, were included in this study. We analyzed the patient's medical records and ultrasound results retrospectively. Results: Among the 1,000 patients, 58.4% were male and 41.6% were female. The mean age of the patients was $4.7{\pm}4.0$ years. The main reasons for ultrasound were abdominal pain (43.9%), vomiting (17.3%), elevated liver enzymes (11.8%), and jaundice (9.8%). Abnormal ultrasound findings were present in 57.9% of cases. The major abnormal findings were mesenteric lymphadenitis (29.2%), fatty liver (12.1%), hepatitis (6.4%), hepatosplenomegaly (6.2%), and acute appendicitis (4.8%). The time interval between the initial medical evaluation and the ultrasound evaluation was within 24 hours in most cases (78.5%). The main findings in children with abdominal pain were mesenteric lymphadenitis (32.6%), fatty liver (5.9%), intussusception (2.7%), and acute appendicitis (2.7%). The main findings in children with vomiting were mesenteric lymphadenitis (12.7%), hypertrophic pyloric stenosis (10.4%), and acute appendicitis (3.5%). The major ultrasound findings in children with urinary tract diseases were hydronephrosis (45.4%), urolithiasis (21.5%) and cystic renal disease (18.1%). Conclusion: Ultrasound examination played an important role as a non-invasive and prompt screening examination for detection of abdominal diseases. Ultrasound was an important tool for pediatricians to determine timely information for patient management.

Background: Circulating levels of brain natriuretic peptide (BNP) provide prognostic information for patients with heart failure. The aim of our study was to investigate whether preoperative and postoperative BNP levels could predict postoperative complications and outcomes in patients after coronary artery bypass graft (CABG). Material and Method: Data was collected prospectively on 30 patients (M/F=19/11, age $60.0{\pm}9.6$ years) undergoing conventional CABG during a 1-year period beginning on January 1, 2005. Patients underwent off-pump CABG, and combined surgery was excluded. The BNP assay was performed preoperatively, immediate postoperatively at the intensive care unit (ICU), and 1, 3, 5, and 7days postoperatively. Result: Preoperative BNP levels significantly correlated with preoperative echocardiographic ejection fraction and an ICU stay of 5 days or more (r=-0.4, p=0.028; r=0.39, p=0.031, respectively). A preoperative BNP cut-off value above 263 pg/mL demonstrated high specificity (90.5%) for predicting postoperative complications using the receiver operating characteristics curves. Preoperative and postoperative (7 days) BNP levels were different depending on the abscence (mean BNP=$99{\pm}23\;pg/mL$ vs. $296{\pm}74\;pg/mL$, p<0.05) and presence (mean BNP=$212{\pm}29\;pg/mL$ vs. $408{\pm}23\;pg/mL$, p<0.01). Conclusion: Preoperative BNP levels >263 pg/mL predict postoperative complications in patients receiving CABG.
